Option Restrictions
NOTE
Brocade recommends you disable a switch before downloading a configuration file. If you plan to
download a configuration file while the switch is enabled, refer to Configuration download without
disabling a switch on page 263.
-fid FID -sfid FID The FID must be defined on the switch and the source FID must be defined in the downloaded configuration file.
-all The number of switches or FIDs defined in the downloaded configuration file must match the number of switches
or FIDs currently defined on the switch.
The switches must be disabled first. If they are not, the configDownload command will download the configuration
for as many switches as possible until a non-disabled switch is found. If a non-disabled switch is found, the
downloading process stops. Before running the configDownload command, verify if any switches must be
disabled.
If you are performing a configuration download due to a configuration error, it is highly recommended to run the
configDefault command before running the configDownload command. Refer to Configuration download without
disabling a switch on page 263 for more information on non-disruptive configuration downloads.
If Virtual Fabrics mode is enabled, the chassisDisable and chassisEnable commands are used to disable all logical
switches on the affected switch. This process bypasses the need to disable and enable each switch individually
once the configuration download has completed.
Non-Virtual Fabric configuration files downloaded to a Virtual Fabric system have a configuration applied only to
the default switch. If there are multiple logical switches created in a Virtual Fabric-enabled system, there may be
problems if there are ports that belong to the default switch in a Virtual Fabric-disabled system, but are now
assigned to logical switches in a Virtual Fabric-enabled system. Only configurations related to ports within the
default switch are applied.
If you must set up your switch again, run the commands listed in Table 57 and save the output in a file format. Store the files in a safe
place for emergency reference.
TABLE 57 CLI commands to display or modify switch configuration information
Command Displays
configShow System configuration parameters, settings, and license information.
fcLunQuery LUN IDs and LUNs for all accessible targets.
fcrRouterPortCost FC Router route information.
fcrXlateConfig Translate (xlate) domain's domain ID for both EX_Port-attached fabric and backbone fabric.
fosConfig Fabric OS features.
ipAddrShow IP address.
isnscCfg Configuration state of the iSNS client operation.
licenseShow License keys installed with more detail than the license information from the configShow
command.
portCfgEXPort EX_Port configuration parameters.
portCfgVEXPort VEX_Port configuration parameters.
CAUTION
Though the switch itself has advanced error checking, the configdownload feature within Fabric OS was not designed for users
to edit, and is limited in its ability. Edited files can become corrupted and this corruption can lead to switch failures.
NOTE
If you download a configuration file with either the portCfgEportCredits or portCfgFportBuffers entries manually removed, the
switch will retain the existing configuration even after configuration download.
